, To aldil whom it may concern: l

Be it known that we,-HERMAN L. WAL- United States of America, and residing at Cleveland,vin the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Terminal Casings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such las will enable others skilled in the art to which it pertains to make and use the same. K

This invention relates to improvements in terminal casings or junction boxes for conl connections between the nections between electric conductors and particularl to terminal casings which are employed tibr supporting and protecting the underground and overhead conductors.

Theobject of the Ainvention is the provision ofv a terminal casing or junction box ywhich canbe easily and cheaply manufac-` tured, which will exclude snow and rain from the connections, and which is ,so yconstructed that access can be readily had to the connections and or of arcscommunicating between conductors or terminal blocks is minimized.

Incarrying out our invention we provide a Y termmal` easing comprising two main members, namely, an insulating support or body which is designed to be secured to any suitable supportmg member such as an upright pole and carries the connections and a bell (or cover which is also preferably formed of insulating material and is designed to t nicely over the' insulating supporting body and toprotect the conductors and connections.` The insulating support has a suitable socket which extends yuplwardly from the bottom thereof and through which the main or underground conductors are ada ted to be broughtfand the wall is provided With laterally" extendingV spaced openings through w'hich'said conductors extend, and near the top of this insulating supporting member on the exterior thereof arersecured terminal blocks having sockets for the ends of the main conductors and also for the `ends of overhead and other branch conductorsl which extend from the terminal blocks downwardly and are brought out from the bell or covernear the lower end thereof. The insulating support is also provided with spaced wings which extend outward A`from the insulating support and the danger of leakage `tending lugs adapted to extend. on opposite sides-of these outwardly projectingfwings. The invention may be further brieliy summarized as consisting in certain novel details of construction and combinations and arrangements of parts which will be de scribed in the specification and set forth in the appended claims.

For an understanding of our invention referencesis yhad to the accompanying draw- -ings inlwhichl j Figure l is a side view of our improved terminal casing'ork junction box secured t-o an upright pole. Fig. 2 is an enlarged Vertical sectional view throughthe terminal casing. Fig. 3 is of the same substantially along the line 3-3, F ig. 2, looking in the direction indicated bythe arrow. F ig. 4 is a transverse sectional view of the same substantially along the line 4-4, Fig. l, looking in the direction indicated by the arrow. l? ig. 5 is a view with the bell or cover removed.

Referring nowv to the gures of the drawings, 10 represents as a whole the terminal vertical pole or post 11 by members to Vbe referred to presently. As was before stated the terminal casing consists of two principal parte, an insulating lsupport or body portion 12 and a bell or cover 13, each of which is made from some suitable insulating material preferably porcelain. The terminal casing is secured to the pole 1l by means of a clamp consisting in this case of two 'semicircu ar straps 14 and 15 which encircle the lower portion-of the insulating support 1 2 which at this point is c lindrical and is redud in size, the end or these straps havin@r -outwardl extending ears which are secure v together y screws 16, and the strap 15 having a laterally projecting stud or shank 17 which is threaded and 1s secured into thev pole. To prevent the insulating supporting member from turning in the straps, the

.former is provided on its periphery with a a transverse sectional viewlcasmg or junction box which is lsecuredto a lug or rib a (see 4;) which extends or ts into a suitable depression of corresponding shape `in the strap 15. Y

r1`he supporting member 12 is'hollow for sthe greater portion of its length being prov downwardly extending socket 19, the two sockets 18 and 19 being separated by a partition or wall 20. The sidewall of the supporting member 12 'is provided with a` number of circumferentially `spaced upwardly inclined openings 21 extending outwardly from the socket 18 near the upper end thereof, there beingn this case three of these openings 21 spaced one hundred and twenty degrees apart, although the number of the openings may be varied 'to suit requirements. As was before state-d, the underground con.- ductors are designed to be brought upwardly through theV lower socket 18 and these conductors, which,^are shown at 22, are inclosed in a lead or suitable casing 23 which extends upwardly ,for a suitable distance into the socketl18. A short distance below the openings 21 the conductors 22 are dvided and each extends outwardly through one of theopenings 21 and at its upper end is secured in a socket of a terminal block 24 by means of a set screw 22a. Ir1`he terminal blocks, the number of which depends, of course', on the number of connections and conductors which the terminal ,casing is to accommodataare secured to the exterior of the supporting member 12 near theypupper end thereof by` means of bolts 25 which ex- -tend'through the wall and have their inne;`

ends in the'upper soclet 19. The blocks 21 are held from movement about the screws by dowel pins or other projections 24a which extend in Suitable openings in the member 12.l rlhese Vterfrpilnal blocks are ar-r ranged above the corresponding openings 21 through whichthe conductors-extend and, are therefore equally spaced. rlhe inner ends of the bolts 25 together with the nuts on the ends are located in .recesses as shown and areseparated by outwardly projecting portions 26 in the socket 19 which prevent the nuts from' turhing in the sockets.` After the terminal blockshave been secured in place, this socket 19 is preferably filled with suitable insulating material which, for the,`

sake ofclearness, is notlshown in the drawinfrs. y

trlhe. overhead conductors to which the underground conductors 22 are designed to lbe connected, are shown at 27, the end of each of these conductors being secured by a set screw 28 in a suitable socket in ione of the terminal blocks and from the termmal 1. Jtninsulating support andere blocks extending downwardly as ywill be ex'- plained.

Extending radially sulating supporting member 12 between the openings 21 and between the terminal blocks 211 are a number of wings 29 which are in this case three in number and are spaced one hundred and twenty degrees apart.. The

.purpose of these wings will be explained presently.,

The insulating bell or cover 12, which, as stated before is preferably formed of porcelain, is substantially cylindrical in shape and extends down over the insulating supporting member l2 a suitabledistance so as to exclude rain and snow from the connections. 'llhis bell or cover is provided at its upper end., which is closed, and on the interior, with a socket 30 which receives theupper end of the insulating supporting member 12. The bell or cover is inwardly extending lugs 31, the lugs of Aeach pair being on opposite sides of one of the outwardly extending wings 29 so as to properly locate or'center the bell or cover. At

outward from the in-` provided also on the interior with .equally spaced pairs of y the lower edge of the bell are three U-shaped slots 32 and through these slots the conductors 27 are brought out from the interior of1 the bell, as shown most clearly in Fig. 1. 1t will be seen that these wings 29 on the insulating supporting member 12 divide the interior space between the the bell into three chambers, each of which contains one of the terminal blocks 24, the end of one of the undergroundlconductors 22 and the end of the one of the overhead? member 12 .and

conductors 27, and that these wings, therefore, act as barriers to prevent arcs communicating between the terminal blocks or conductors. Furthermore the construction and arrangement are such that not only is moisture eHectively excluded from the connections, but the bell may be readily lifted from its normal position in case it is desired to inspect, repair or change any of the connections. Furthermore the parts can be cheaply manufactured inasmuch as both the insulating supportin member 12 and the tbell can be molded from porcelain or any other Fdesired insulating material, and can be assembled without any machining .or altering being necessary. Also the conductors body portion, aterminal block secured to the.. body portion above each oneningmrd an im.
